A bubble bursts NASA/JPL PHOTO RELEASE Posted: April 18, 2005 RCW 79 is seen in the southern Milky Way, 17,200 light-years from Earth in the constellation Centaurus in this spectacular image from the Spitzer Space Telescope. The bubble is 70-light years in diameter, and probably took about one million years to form from the radiation and winds of hot young stars.
NASA's Spitzer Space Telescope easily detects infrared light from the dust particles in RCW 79. The young stars within RCW 79 radiate ultraviolet light that excites molecules of dust within the bubble. This causes the dust grains to emit infrared light that is detected by Spitzer and seen here as the extended red features. |
